Some of the specimens very fine, and much larger than Eu- 

 ropean ones. This species is widely distributed, and in appearance 

 is very variable. 



If De Notaris's name has priority in publication, it ought to 

 take precedence. 



S. ruralis, Linn. 



Hab. Rocky Mountains, Cascade Mountains, Fort Colville, and Moyie 



River (a branch of the Kootenay), Lyall. 

 This species is generally present in collections from very high 

 northern latitudes. 



S. l^evipila, Brid. 



Hab. Vancouver Island, Lyall. 



A short compact state, but not apparently different from the 

 European form. M. Lesquereux makes the same remarks upon 

 the Californian specimens sent to him. 



S. papillosa, "Wils., has been sent from "Boston intermixed with 

 JPterogonium intricatum, Hedw.
